Regioselective formylation or acylation of isoprene at the C1 atom was realized by reaction of Cp2Zr(isoprene) with saturated esters followed by protonolysis with acetic acid. The corresponding reaction with various alkyl acrylates resulted in the formation of allyl vinyl ketones.
α-Methoxyallyl sulfides prepared from methoxy(phenylthio)methane proved to be a novel acylanionequivalent providing a new synthetic method for α-methylenated ketones.
